@flows Feature: Lunar Proxy - rate limit Background: Starts the Proxy Given Lunar Proxy is down And API Provider is up And Lunar Proxy env var `LUNAR_STREAMS_ENABLED` set to `true` And Lunar Proxy is up Scenario: When basic rate limit flow is active, quota metrics shows limit and used value When Basic rate limit flow created for httpbinmock/* with 5 requests per 1 seconds And flow file is saved And resource file is saved And load_flows command is run And next epoch-based 1 seconds window arrives And 4 requests are sent to httpbinmock /headers through Lunar Proxy Then There is a counter named lunar_resources_quota_resource_quota_limit with the value 5 And There is a counter named lunar_resources_quota_resource_quota_used with the value 4 And There is a counter named active_flows with the value 1 And There is a counter named flow_invocations with the value 4 And There is a counter named requests_through_flows with the value 4 And There is a gauge avg_flow_execution_time with the value larger than 0 And There is a gauge avg_processor_execution_time with the value larger than 0
